The backrest of the chair can be perfectly adjusted like a car seat. So you have lots of options here too.

I upgraded my chair because I was experiencing back pain from a previous chair. Everything in the box is well packaged and doesn't fell like a cheaper knockoff brand at all. his chair has helped my back tremendously. Everything else is top notch and I highly recommend if you are sitting for long periods.

I like the chair, however, having a separate cushion for the lumbar support doesn't really work well. It fell over every time I got up. There should be lumbar support built into the back of the chair. I also had to add an ergonomic seat cushion because the seat was very hard. This solved the issue of the lumbar support falling down when I got up because I tucked it behind the seat cushion to hold it in place, but the lumbar support at that low height resting directly on the chair is way too low for a proper lumbar support. It would be well worth paying more for a chair with the lumbar support in the chair and a much softer seat cushion. I like the way the rest of the chair functions, such as the arm rests and way the sides of the chair wrap around.
